1952 Map of Eden Valley

About this map

Mt Sanhedrin anchors the southern portion of this rugged landscape within the Mendocino National Forest, where steep ridges and deep canyons define the transition between the Eel River and high interior peaks. The 1952 field survey shows a landscape dominated by livestock ranching and wildland transit, centered on the Eden Valley Ranch and the open pastoral ground of Eden Valley. Movement through the backcountry relied on established routes like the Thatcher Trail and Jack Hall Trail, which connected isolated landmarks such as Four Pines (Site) and Sportsman Glade. The northern reach includes a portion of Round Valley, while the central terrain is marked by distinctive geological features like Impassable Rock and Thatcher Butte. This era represents the mid-century forest management period before modern highway development significantly altered local access.
